Hi doctor,

I have hemorrhoids for a few years. My doctor has suggested me a colonoscopy to rule out cancer. Is there any simple test available to rule out colon or rectal cancer? Please mention an opinion regarding stool occult blood test.

Hi,

Welcome to icliniq.com.

First of all, you get an MRI (magnetic resonance imaging) abdomen done. You can have a presence of mass when you have a colon or rectal cancer. If there is a mass seen, then you can do a colonoscopy. You can also do a CEA (carcinoembryonic antigen) as CEA show an increase in range when you have colon cancer. You can also do a stool DNA test. If the stool DNA test is positive, then you can also do a colonoscopy to confirm the diagnosis.

Thank you doctor,

Please mention an opinion regarding stool occult blood test. Can I have bleeding daily in colon cancer as same as hemorrhoids?

Hi,

Welcome back to icliniq.com.

Bleeding in colon cancer or hemorrhoids does not have a fixed pattern. If the stool occult test is positive, then colonoscopy can be done to rule out the disease. A stool DNA test is a more specific test for diagnosing it. Colonoscopy is one of the most precise analyses done to diagnose colon cancer. It is very safe and painless nowadays.
